Rosa Valencia is an acid-sensitive limestone. Wine, lemon juice, vinegar, cola, sanitary cleaners or descalers leave etch marks on the material surface — visible as matt shadows or a loss of gloss.
For all applications an impregnation on a silane or polysiloxane basis is mandatory. It prevents the penetration of water, oil and colouring agents and reduces the formation of stains — but it does not remove the acid sensitivity. On polished surfaces we recommend renewing the impregnation every 1-2 years, more frequently on heavily used floor surfaces.
Daily care is carried out with a pH-neutral natural stone cleaner and a soft microfibre cloth. Avoid vinegar cleaners, cement veil removers, acidic sanitary cleaners and strongly alkaline agents. Wine, coffee, oil, lemon juice or cosmetic products should not be left to act on polished surfaces for long — wipe them up immediately and wipe over with clear water.
For kitchen worktops Rosa Valencia is only suitable to a limited extent — acids from everyday cooking can leave a visible patina. Anyone who loves the warm material image and accepts the patina as character can use the material. Anyone who needs maximum everyday security should choose a warm-toned quartzite or granite.
Rosa Valencia is primarily an interior material. Frost resistance is only given to a limited extent; for permanently weathered external surfaces the material is not to be recommended. In protected external locations with a honed surface and appropriate laying, a moderate load is possible.
